Climate Protection Act Schleswig-Holstein

Hi

At the moment I am facing a problem. From 1.7.22 the new climate protection law applies in Schleswig Holstein. My house was built at the end of the 60s and so far only insulated on the roof. At the moment I have an oil heating system that is about 20 years old and would certainly still run for 5 or 10 years. After that I would have switched to gas. But this new law changes everything. Because after 1.7 I will not easily get approval for a gas heating system. It is also difficult to find information or options; the law states that 15% of the heating energy must come from renewable energies. And none of the options seems to work in my situation. Here is a list of the options and my problems with them.

Gas heating with a supplier contract with biomethane share. / not possible because my hot water supply works via an instantaneous water heater. In this case the hot water supply must also be 15% from renewable energies.

Photothermal / My roof is already full with a photovoltaic system.

Heat pump / my insulation is too poor for this (although I have an air conditioner in the bedroom that can also heat).

Additional pellet stove / I have a large pellet stove in the living room but 30% of the total living area must be heated with it. That would mean I would have to remove the doors in the living and bedroom.

The hot water supply with instantaneous water heater is already the most sensible solution for me because I live alone and am often out in the field. Thus the hot water consumption is very low and is also generated by the photovoltaic system.

Perhaps someone knows a solution on how to meet the 15% requirement?

I would prefer not to have the heating system changed in a rush. Although I don’t even know how quickly the gas connection can be installed in the house.

I am grateful for any response.

Regards

Sebastian

Would someone perhaps still know a solution on how to fulfill the 15% requirement?

Since you don’t want to replace your current oil heating system at all - you write that you would replace it after 5-10 years - you still have 5-10 years to think about it. One concrete possibility is a gas heating system with a gas supply contract for biogas. Otherwise, it also applies: If implementation is not possible for technical or structural reasons, a disproportionate effort arises, or a particularly preserve-worthy building fabric exists, the obligation to use can be waived. So dear Sebastian, take a deep breath and relax. It’s not such a big deal.

Thank you for your response. The problem is, if in 5 years I have a gas heating system installed with a biogas contract, I am also obligated to generate hot water through the heating system. This would significantly increase the costs, in addition to the probably more expensive biogas. The question of what is disproportionate is also very flexible.

Photothermie / Mein Dach ist schon voll mit einer Photovoltaik Anlage

Here I see the best point of connection. You don’t necessarily have to mount it on the roof, there is often space on the facade. Or elevated on the flat roof of the garage. I have also seen some installed on a retaining wall. With a bit of creativity, a place for solar thermal can definitely be found.

Thank you for the response. Solar thermal would be very difficult to implement. It is a hip roof bungalow in a rectangular shape. The south side is fully covered with photovoltaic modules, the north side is shaded. The east and west sides are too small. The garage is at basement level and hardly gets any light. Wall mounting is also not possible because of the large windows. The only option left would be to set something up in the garden, but would that still be economical?

The pellet heating system would be an option
